system%28Y=2x%2B5%2CY=2x%5E2-x%2B3%29

Y=Y

2x%2B5%22%22=%22%222x%5E2-x%2B3

0%22%22=%22%222x%5E2-3x-2

0%22%22=%22%22%282x%2B1%29%28x-2%29

2x%2B1=0,   x-2=0
2x=-1,    x=2
x=-1%2F2

Y=2x%2B5        Y=2x%2B5
Y=2%28-1%2F2%29%2B5    Y=2%282%29%2B5
Y=-1%2B5         Y=4%2B5 
Y=4            Y=9

Two solutions:  

(x,y) = %28matrix%281%2C3%2C1%2F2%2C%22%2C%22%2C4%29%29

(x,y) = (2,9)
